**Issue Description:**
Due to changes in field access rights verification as seen here:
https://github.com/odoo/odoo/blob/494231e796b562162d3bfb19fc8ce7550657cf07/odoo/models.py#L5334-L5345
And the removal of sudo rights for CrmLead:
https://github.com/odoo/odoo/blob/494231e796b562162d3bfb19fc8ce7550657cf07/addons/website_crm_partner_assign/controllers/main.py#L98
Attempting to open a search by domain with the `activity_date_deadline`
field triggers a 403 error:
"You do not have enough rights to access the fields
'activity_date_deadline' on Lead/Opportunity (crm.lead). Please contact
your system administrator."
**Steps to Reproduce:**
1. Install the `website_crm_partner_assign` module.
2. Assign Joel Willis a partner level (via the partner assignment tab in
the `Contact` app).
3. Navigate to CRM, select an opportunity, and assign it to Joel Willis
(using the assigned partner tab in the lead form).
4. Log in to the portal as Joel Willis, navigate to Opportunities, and
click any filter on the activities date `Overdue / today / this week
activities`. This action results in a crash.
**Proposed Solution:**
Since we assume that the domain will always filter opportunities with
assigned to current user, we can:
- Do a first search using sudo with the original domain that might
contain the `activity_date_deadline` field.
- Then do a regular search with the opportunities IDs obtained from of
the first search.
